This calculator finds the direction angle of a vector and calculates a unit vector in this direction. Vectors are a powerful tool to represent many physical quantities in our physical world. They represent forces, velocities, and many other quantities derived from them. With this tool, you can ...
Answer to: 1. Find a unit vector which points in the opposite direction to the vector A = {2,1,-2}. 2. Calculate the component of a = {2,3,4} in...
Vector Addition:Vector addition of two vectors can be done by following the laws of vector addition like triangle law of vector addition, parallelogram law of vector addition, etc. If two vectors are given in the form of unit vectors, then the...
Find a vector {eq}\displaystyle u {/eq} that has the opposite direction to the vector {eq}\displaystyle v = (1,0, -t), \ t \in \mathbb{R} {/eq}, and {eq}\displaystyle \mid \mid u \mid \mid=1 {/eq}. Vectors in {eq}\mathbb{R^...
Another application of the cross product leads to the last column vector of the rotation matrix Rc, that defines the y direction t→‖, see Eq. (26). Sign in to download hi-res image Fig. 15. Determination of the crack normal n→crack. The triangle, for that t→c is computed, is ...
// between [-2*PI, 2*PI](negative angle means a // reverse result vector). So it exists a potential // candidate, say, maybe actuall 150degree if we // get a result of 30degree. // // The Dot Product(innerproduct) is a good way to ...
The subtraction of two vectors is a particular case of vector addition. In effect, the subtraction of vector B minus vector A is equal to the sum of vector B plus the opposite vector of A. If the vectors are coplanar, then it is feasible to use graphical methods. ...

var fwdSpeed = Vector3.Dot(rigidbody.velocity, transform.forward); Naturally, the direction can be anything you like but the direction vector must always be normalized for this calculation. Not only is the result more correct than the magnitude of the velocity, it also avoids the slow square...
A simple way to calculate the directional derivative is with the dot product of the unit director vector by the gradient vector of the function: {eq}\,\,\,{D_{\hat v}}f\left( {x,y} \right) = \nabla f\left( {x,y} \right) \c...
